Abstract: A headphone includes: a headband; a sound emitter having a sound-emitting unit therein; and a connector connecting the sound emitter to the headband. The connector includes: a support for supporting the sound emitter so that the sound emitter is rotatable in a predetermined rotation range including a reference position; a restoring portion for applying a restoring force on the sound emitter for urging the sound emitter to return to the reference position; and a switcher for switching a state in which the restoring force acts on the sound emitter and a state in which the restoring force does not act on the sound emitter.

Abstract: A management apparatus includes a display controller to display a configuration of a system including a management target device and another management target device managed by another management apparatus such that a relationship between the management target devices is indicated.

Abstract: An ink supply apparatus includes a first ink tank, a second ink tank, a first flow path configured to connect the first ink tank and the second ink tank, a volume change unit disposed on the first flow path, configured to be able to change an internal volume of its own, and allow ink to flow thereinto from the first flow path when the internal volume is expanded and to flow out to the first flow path when the internal volume is reduced, a first opening and closing unit disposed between the first ink tank and the volume change unit, and a second opening and closing unit disposed between the second ink tank and the volume change unit.

Abstract: A supply apparatus includes a holder for a liquid container, a link coupled to the holder, an operation handle rotatably coupled to the link, an engaging portion and a rotation restriction unit. The operation handle operate connection and disconnection of the liquid container to and from a supplying portion by rotation with respect to the link. The engaging portion maintains a connection state between the supplying portion and the liquid container by engaging with the operation handle. The unit can restrict rotation of the operation handle when the engaging portion and the operation handle are in a disengaged state.

Abstract: Provided is a liquid holding container in which waste liquid leakage is not caused even when the container is turned upside down. For this purpose, a surface of an absorber facing the rear face of a cover part is disposed apart from the cover part so as to form a space between the cover part and the absorber of a waste liquid holding container.

Abstract: There is provided a print device including a wet liquid supply unit corresponding to a wider environmental range, with a simple and inexpensive configuration. Therefore, a valve that can change the volume is provided in a flow passage between an intermediate tank and a storing unit that stores liquid and that supplies the liquid to the intermediate tank.

Abstract: An ultrasonic diagnostic apparatus includes a controller, to which a probe and a monitor are connected, the probe having an array of transducers, in which a number of transducers are arranged in a first direction. The controller controls transmission of an ultrasonic beam using the array of transducers and reception of an echo signal reflected from a region of interest, generates image data based on the echo signal, and gets echo signals received from multiple points of the region of interest by either moving or swinging the array of transducers in a second direction that intersects with the first direction at right angles. If the sum of image data ranges of measured value retrievable portions of the region of interest at the multiple points synthesized based on the echo signals, is equal to or greater than a predetermined value, the controller calculates a detected value of the region of interest.

Abstract: An ultrasonic diagnostic apparatus that enables even an unskilled person to get accurate detection done is provided. The ultrasonic diagnostic apparatus includes a controller, to which a probe and a monitor are connected, the probe having an array of transducers, in which a number of transducers are arranged in a first direction.
